need part numbers or where to find parts

[flexo]

Does any one know if these seals/hoses cross over and or if any one has some for sale:
Rear differential pinion seal
Transmission output shaft seal
Shifter housing seal
Heater core hoses
Rear Hicas lines

Rear differential pinion seal (i think the 240sx is the same from my understanding)
Transmission output shaft seal (should be a 300zx)
Shifter housing seal (black gasket maker) Works great
Heater core hoses (top you can match the bend from prebent stuff at lordco. Don't have the part number from mine The bottom is skyline specific ask an importer. or ebay if you want to try to silicone ones autobahn makes)
Rear Hicas lines (Pull all the hicas junk out throw it away and buy yourself a lockout bar)
